Eurasian Eagle-Owl
Contour feather, likely from the dorsal (back) or scapular region

Eurasian Eagle-Owl

Kingdom: Animalia; Phylum: Chordata; Class: Aves; Order: Strigiformes; Family: Strigidae; Genus: Bubo; Species: Bubo bubo

Family: Strigidae (Typical Owls)

Shape
Broadly spatulate with a rounded tip; largely symmetrical vanes typical of body plumage rather than flight feathers
Size
Approximately 15 cm in length as reported, which is consistent with the large scapular or upper-wing covert feathers of a bird of this magnitude
Rarity
Uncommon. Though the population is stable in France, they are elusive, nocturnal, and have large territories, making feather finds noteworthy

Description

The Eurasian Eagle-Owl is a massive predator with a wingspan up to 188cm. This feather exhibits the classic 'eagle-owl' spotting—large white patches against a rufous-brown background. Known as the 'Le Grand-Duc' in France, the bird features prominent ear tufts and striking orange eyes

Colour & Pattern

Base color is a warm tawny-buff to clay-brown, marked with distinct, irregular white 'blotches' or spots on the inner and outer vanes. Darker brown horizontal mottling is present toward the tip

Barb Structure

Highly specialized; the proximal half is extremely plumulaceous (downy) for insulation, while the distal half is pennaceous but features a soft, velvety pile for silent flight

Texture & Surface

Extremely soft, silky, and matte. Lacks the oily gloss of waterfowl; the surface feels like velvet due to 'frizz' on the barbules that dampens sound

Key Features

Large size (15cm for a body feather), velvety texture, and the specific pattern of bright white semi-rectangular spots on a buffy-brown background

Habitat

Ecologically versatile but prefers rocky outcrops, cliffs, and old-growth forests offering plenty of prey and nesting ledges. Common in the crags of Bourgogne

Geographic Range

Found across much of Europe and Asia. In France, they are resident year-round, particularly in regions with suitable cliff faces or sparse woodland

Ecological Role

Apex predator. They regulate populations of medium-sized mammals and birds. Their presence indicates a healthy, complex ecosystem with sufficient prey biomass

Similar Species

Common Buzzard (Buteo buteo) feathers are stiffer and lack the velvety 'owl' texture; Tawny Owl feathers are much smaller; Great Horned Owl is North American only

Interesting Facts

It is one of the largest owl species in the world, capable of preying on animals as large as roe deer fawns or other raptors like Buzzards and Peregrine Falcons

Condition Notes

Good condition. The plumulaceous base remains voluminous. Slight separation of barbs on the right specimen indicates natural wear or stress during molting

Notes

In Bourgogne 15cm long Not a common buzzard
